HIGH POWER DENSITY DEVELOPMENT PROJECT INTERIM REPORT 300 MWe HPD CONCEPTUAL DESIGN STUDY

摘要

The fuel assembly incorporates several novel, cost reducing features which, on the basis of fuel cycle cost estimates, compares very favorably with the standard BWR.nThe core support structure employs a unique fabricating technique which reduces costs and allows the use of thinner control rods. A consequent Í5 per cent reduction in the overall design hot-spot factor due to less local flux peaking, was therefore assumed.nThree control rod concepts, all with an overall thickness of 0.25-inch, have been designed.
